Updates on withholding tax and stamp duties (2026)
- Entreprises
Withholding tax and stamp duties repeatedly raise challenging questions in practice - particularly with regard to the recognition of capital contribution reserves, non-cash benefits in a group relationship and the tax treatment of fiduciary relationships. Using practical case studies, Thomas Jaussi and Markus Küpfer show which requirements must be met for a tax-free distribution from capital contribution reserves in accordance with Art. 5 para. 1bis of the Swiss Federal Tax Act (VStG), when a refund of turnover tax is possible following a change in FTA practice and how non-cash benefits are to be assessed in the case of an intra-group sale of a shareholding. The solutions provide you with the necessary tools to recognize and correctly assess typical stumbling blocks in withholding tax and stamp duties.

Current cases on intercantonal and international corporate tax law (2026)

The determination of tax domicile and the delimitation of permanent establishments are among the most challenging issues in intercantonal and international corporate tax law - especially in constellations with home offices, cross-border infrastructures or competing cantonal tax jurisdictions. Using practical case studies, Philipp Betschart and René Matteotti show how the place of effective management is to be determined, when home office activities constitute a permanent establishment and how profits are to be separated internationally according to the Authorized OECD Approach. The importance of sovereign rulings in the assessment procedure and revision claims in the case of intercantonal double taxation are also dealt with. The solutions provide you with the necessary tools to confidently assess jurisdiction and separation issues and to recognize tax risks at an early stage.

Current problems of taxation of stock corporations and shareholders (2026)
- Entreprises
- Individuals
The tax treatment of employee shares, the application of minimum taxation (Pillar II) and the valuation of securities and participations in the balance sheet raise complex demarcation issues in practice - particularly in the light of recent Federal Supreme Court rulings. Based on practical case studies, Oliver Jäggi and Remo Küttel show how treasury shares are to be treated for profit tax purposes when sold to employees, which Swiss group company is considered a business unit subject to supplementary tax and under which conditions value fluctuation reserves and value adjustments on participations are recognized for tax purposes. It also deals with the calculation of property gains tax in the case of hidden capital contributions among majority shareholders. The solutions provide you with the necessary tools to implement current developments in profit tax, Pillar II and real estate gains tax in practice.

News on the taxation of corporate restructurings (2026)
- Entreprises
In practice, corporate restructurings raise a variety of tax issues - in particular when shareholdings are spun off, real estate is converted, sister companies with loss carryforwards are merged or demergers are completed by selling at a lower price. Using practical case studies, Stefan Oesterhelt and Daniel Strahm show what tax consequences are associated with the spin-off of participations (including minority participations of less than 10%), when it is possible to invoke Art. 12 para. 4 lit. a StHG for real estate gains tax and under what conditions the conversion of an ordinary company into an AG can be tax-neutral. It also deals with mergers with loss carryforwards and cantonal differences in Basel, Berne and Zurich. The solutions provide you with the necessary tools to plan complex restructurings safely and to recognize tax obstacles at an early stage.
The VAT assessment of subsidies, brokerage services and restructurings is one of the most challenging areas of VAT practice - especially in the case of state-financed foundations, finder's fees in the financial sector or the transfer of real estate within a group. Using practical case studies, Ralf Imstepf and Roger Rohner show when grants qualify as subsidies, under what conditions mortgage and capital brokerage is exempt from tax and how the transfer of business and investment properties should be handled correctly in the notification procedure. The solutions provide you with the necessary tools to recognize typical stumbling blocks in subsidies, financial services and restructuring and to assess them correctly for VAT purposes.
In practice, the tax exemption of associations and foundations on the grounds of charitable status raises numerous demarcation issues - especially when entrepreneurial activities, the holding of participations or entrepreneurial support models come into play. Using practical case studies, Claudia Suter and Andrea Hildebrand show where the boundaries of permissible entrepreneurial activity lie, under which conditions holding foundations remain tax-exempt and how funding instruments such as shareholdings, convertible loans or impact investing are to be assessed. The tax exemption of private schools and the requirements for international grant-making foundations with multi-level activity phases are also covered. The solutions provide you with the necessary tools to confidently assess the requirements for tax exemption and avoid typical stumbling blocks in the approval and review process.
The comprehensive PDF (+530 pages) combines all solutions to the case studies from all five workshops of the seminar "Current Tax Issues in M&A Transactions".

These case studies use practical constellations to show how issues such as reporting procedures, tax succession, input tax deduction and company sales should be assessed from a VAT perspective. Among other things, complex restructurings, asset deals and special features of investment and finance companies are dealt with. The solutions provide you with clear guidelines for recognizing VAT risks and handling transactions correctly.
